Swapping Tonearms on a VPI Aries- anyone?

Hi, I have a quick question about my recently acquired Aries. This applies to the original Aries, AND and Aries 3 owners. Read on for the full story.

Right now, I have a SME Series V with a Benz MC Gold, which sounds great. The only problem is, I have a lot of mono LPs that sound MUCH better with my mono cartridge (which has a 1 mil. tip).

With my trusty SME 3009 pre-improved, it was easy to swap headshells. Not so with the series V, as you know.

So, the original Aries has three screws holding the tonearm board down. My questions is, does anyone swap arms regularly on the their Aries? My worry is that constantly swapping will eventually wear out the three holes. If they were threaded, then it would be cool. However the original Aries has three long wood screws.

Now, the next part of the question. FedEx damaged my chassis, so they're buying me a brand new Aries 3 chassis, which, I've been told, has a slightly different armboard. Maybe the Aries 3 has threaded holes for easy armboard swaps?

In a perfect world, I'd use the Series V for stereo, then be able to pop the 3009 pre-improved on in a matter of minutes for mono LPs. (acutally, in a perfect world, I'd have 2 Series V's :-)

Possible?

Thanks!
